kwakman:
you will probably have to use ebay for powervalves but i have found everything else for my 86 after some concentrated web searching.give me a shout if your struggling with anything else.K.
RoostiusMaximus:
Lets talk about the powervalves for a minute, the 86 were steel, the 87s aluminum? what were the 88s?
kwakman:
i was under the impression the valves are aluminium and the rod that drives them is steel hence when glooped up with carbon, the teeth on the valves fail before the rod that accentuates them.the 88 up gears are interchangeable, the 88 cases use a smaller countershaft sprocket bearing than the 89 on models otherwise the bottom ends seem identical.
bleeding green:
thanks guys! so far everything is still good. the one thing i cant seem to find is new foot pegs. mine could definitely use a new set. bike bandit says the oem ones are not available. do you know if the newer kx ones work or is there a universal set that would work? im not picky on brand i just need a new set. thanks!
